Improvement in lubricators



WILLIAM MCCULLY, 0E P A'rEasoN, NEW JERSEY,

Letters Patent No. 87,423, :lated March 2, 1869.

IMPROVEMENT IN ,LUBRICATORS 'l'he Schedule referred to in these LettersPatent and maldng part of the same.

To all whomt may concern Be it known that I, WILLIAM McGULLY, ofPaterson, in the county of Passaic, and State of New- Jersey,

yhave invented a new and useful Improvement in'Lubricators; and I dohereby declare that the following is a full, cleai', and exactdescription thereof, which will enable others skilled in the art to makeand use the saine, reference being had to the accompanying drawing,forming part of this specification.

This invention relates to a new and1 useful improvenient Ain thefmethodof oiling the cylinders of locomotive-engines, but which is adapted tootheruses, and

consists in providing a single cock in combination with anoil-reservoir, and suitable oil-passages, by which the oil orother"lubiicating-material is distributed to each of the cylinders, aswill be hereinafter more fully described. y

The accompanying drawing- Figuie 1, represents a vertical sectionof alubricator constructed according to my invention.

Figure 2 is a front view of the hand-wheel on the outer end ofthe cock,by which the cock is operated.

Similar' letters of reference indicate corresponding parts.

This lubricator is attached to tne end of the boiler, or thelsteam-space thereof, so that steam may be used for forcing thelubricating-material into the cylinder.

Hitherto a separate cock has been employed i'oi lubricating eachcylinder, and also for admitting ste'am thereto, for the'purposes beforenamed.

By my improvement, the engineer is enabled to oil botlli cylinders byturning a single cock, besides admitting the necessary quantity ofsteam.

A represents a glass or transparent oil-reservoir.

B represents the shell or body of vthe cock to which the globe orreservoir A is attached in any suitable manner. .This shell is attac-hedto the boiler by the tubular shank O.

D is the cock.

E is the wheel'on the end of the cock, for turning it to any desiredposition.

It will be seen that the shell B is provided with apertures, which placeit in communication with each cylinder, as f g, and with the boiler, asat It, and with the oil-reservoir, as at t. I A

In the cock D there is a right-angled orifice, j,whicli is made, byturning the cock, to register with either two of the oriiices f, g, 7i,and t. The position of the cock with regard to those orifices isindicated by the projections n it on the wheel E, which correspond withthe orifice j.

On soiiie occasions there will be a back pressure of-\ steam from thecylinder, through the pipes f or g, iiito the oil-holder A. Y To preventunpleasant consequences shouldthis back flow of steam occur, 1 providethe valve O on .therod p, which valve is operated by the steam whichwill strike the disk q as it enters the reservoir, andclose the valves.Oil is admitted into the left-hand cylinder by turn` ing the cock, asseen in the drawing. To make sure that the oil is carried to therequired point, the cock will be turned to the left, onefourth of arevolution, when steam will iiow from the boiler into the tube f, andforce the oil into the cylinder, and the same with the right-haiidcylinder.

1t will be seen that the engineer, instead of turning three or-t`ourcocks, to oil his cylinders, turns only one, and that, when he takeshold of the wheel E, he knows, by the projectioiisn n, just how to turnthe cock, even in the darkest night.

The advantages of this arrangement will be readily understood by all whoare acquainted with the management of locomotive-engines.

. Having thus described my invention,-

I claim as new, and desire to secure by Letters Patentey 1. The cock D,in combination with the shell B and oil-reservoir A, arranged eitherwith or without connections, with the steam-boiler, substantially as andfor the purposes described.

2. In combination with the cock D, the valve 0 in the oil holder A,substantially as and for the purposes herein shown and described. f-

The above specification of my invention signed by me, this 21st day ofDecember, 1868.

WM. MCGULLY.
